I have a research article aimed for popular audience, whose bibliography contains:
- 3 works on borderline personality disorder
- 1 works on language (Hirsh, David, and Paul Nation. “What Vocabulary Size Is Needed to Read Unsimplified Texts for Pleasure?” Reading in a Foreign Language 8, no. 2 (1992): 689–96.)
- 1 vignette and poem book relating to the above topics
What is the correct umbrella term covers those topics, so that I can tag them in my BibTeX file?
